Kylie Jenner's make-up tips for Caitlyn

Kylie Jenner gives Caitlyn Jenner make-up tips.

The 18-year-old reality TV personality is very close to her father - who was known as Bruce Jenner before undergoing a gender transition last year - and loves the fact the 'I Am Cait' star is such a big fan of her own Lip Kits that she even passes them on to her friends.

Asked if she gives Caitlyn advice, she said: "Not on what she should do, but on her style and make-up, yes.

"She loves the Lip Kits and gives them to all her make-up artists and friends. And she's really proud of me because she knows how hard I work."

Caitlyn, 66, recently teamed up with MAC Cosmetics for a new lipstick and beauty campaign and Kylie - whose mother is her manager Kris Jenner - was thrilled with Caitlyn for landing her first make-up deal.

She said: "I love supporting her with things like her new MAC campaign. She was so excited when it was announced and called me immediately so that we could go to dinner and celebrate."

Kylie's Lip Kit sold out within minutes when it launched earlier this year, and has done twice since when the range was expanded, but the brunette beauty admits she never expected it to be such a success.

She told Glamour magazine: "I've been so surprised. I didn't think my Lip Kit would be as huge as it is now - and the fact people can't get it is crazy.

"But my goal wasn't to always have it sell out. I want girls to be able to get it as easily as possible. It's just that no matter how much we make, it sells out even faster every time."
